MECHANISIVI FOR OPERATING CHURNS.

SPECIFICATION forming part of Letters Patent No. 440,158, dated November11, 1890. Application filed October 19, 1889. Renewed October 13. 1890.Serial No. 368,005. (No model.)

To all whom it may concern.'

Be it known that I, JOHN H. HOUSE, a citizen of the United States,residing at Wilton, in the county of Granville and State of NorthCarolina, have invented a new and useful Mechanism for Operating Churns,of which the following is a specification.

My invention relates to improvements in mechanism for operating ohurns,dac.; and it consistsin certain novel features, hereinafter describedand claimed.

In the accompanying drawings, Figure l is a perspective view of myimproveddevice. Fig. 2 is a longitudinal sectional View with a partinside elevation. Fig. 3 is a detailtransverse section.

The frame of myimproved device comprises the base A and the standards OB, at the front and rear ends of the same, respectively. On the upperside of the base, at the front end of the same, I secure the curved ribsD D, between which a churn-body may rest, and by which it is held on thebase. A plate or platform E is secured to the standards B O, and on thisplate, at the side edges of the same, I erect the standards or supportsF, in which I journal a shaft G, on which I secure a balance-wheel H anda double cam I. The driving-shaft Gr is provided at one end with a crankJ, by means of which it may be operated, as will be readily understood.

To the front sides of the standards O, I secure a pair of plates K,which are provided.

in their inner edges with the vertical grooves L, which are engaged bythe edges of a vertically-sliding cross-'head M. This cross-head isprovided at about its center with an opening N, which is engaged by apoint or pin O at the front end of a lever P, which is pivoted to theupper end of the rear standard B.

To the rear side of the standard B, near the lower end of the same, Isecure a downwardlyprojecting hook Q, to which I secure the lower end ofa spring R, having its upper end engaged in a link S', which isadjustably secured to the rear end of the lever P. The lever is providedat about its center, on its upper side, with the shoulder T, which isarranged directly under and in Contact with the double cam I, and isre-enforced by a metallic plate U, to reduce the wear.

The dasher-staff is secured to the front side of the cross-head by meansof a boltVin the cross-head passing through the upper end of thedasher-staft', and a thumb-nut W, mounted on the end of the bolt andturning up against the staff. The staff is prevented fromswinginglaterally by a pin X on the cross-head engaging an opening inthe staff.

In practice the churn-body is placed on the platform or base of thedevice and the cream placed therein in the usual manner. Theoperating-shaft is then rotated, so that the cam acting on the leverwill cause the same to vibrate and thereby reciprocate the dasherstaff,so that the dashers will thoroughly agitate the cream and therebyquickly produce the butter. It will be observed that the cam forces thelever downward, so that the spring will be extended, and consequently assoon as the cam has cleared the shoulder of the lever the spring willresume its normal position and thereby elevate the lever. The pin orpoint at the front end of the lever plays freely in the opening in thecross-head, so that it will not bind therein as the cross-headreciprocates. The guide-plates K cause the cross-head to move in a truevertical plane, and the dasher-staff is held securely to the cross-head,so that it will not sway-and bind against the opening in the lid of thechurnbodv.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

The combination of the supporting-frame, the lever mounted therein,means for vibrating the lever, the hook at the rear end of the frame,and the spring having its lower end engaging said hook and its upper endengaging a link, which is adj ustably secured to the lever, as setforth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two Witnesses.

JOHN H. HOUSE.
